We all may have heard about blue light and how it affects us, but is blue light really a matter of concern? The answer could be both yes and no.
As ironic as it may sound, we all essentially require blue light at day and not so much at night. We need blue light to carry out our daytime activities actively, and at night our bodies require to dose off, and that’s why we don’t need blue light at night.
But how can we not allow blue light to enter our eyes at night or block the excessive exposure? This article will tell you how.
What is blue light, and why is it necessary to block the excessive exposure of it?
Blue light is the light of the visible spectrum emitted from the sun. This blue light is responsible for keeping us alert at day, but at night, this blue light can decrease melatonin expression and cause sleep disruption.
Not only blue light disrupts our sleep, but its extended exposure can have various detrimental effects on our eyes and our general health too.
That is why it important to find measures to block or filter the untimed and excessive blue light exposure.
Blue is present everywhere, and practically it is impossible to avoid the blue light exposure all day. Sun is the blue light source at day, and at night the digital screens and LEDs we use are a root of blue light.
We need to filter out the ‘unnatural’ and ‘untimed’ blue light sources.
What are the sources of unnatural blue light emission?
The amount of time I spend staring at my phone and the computer screen is impossible to quantify. Isn’t this the case for all of us? During the day, most of us are bound to work on our computer screens, and at night we can’t sleep without scrolling our news feeds.
Millions of us are now obsessed with our digital devices so much that we need them for proper day to day functioning.
Not only our digital devices but our night time illumination sources like LED and fluorescent bulbs emit blue lights too, and it essential to filter it out also.
How can I filter of excessive exposure blue light?
There are specific measures that we can adopt to block stop the blue light providing harm to us.
Keeping our phone away near bedtime hours
According to Harvard Health, blue light exposure in bedtime hours can directly disrupt our circadian rhythm. In turn, this disruption can cause various sleep problems like trouble sleeping or staying asleep or even insomnia.
We can swap our nighttime phone scrolling to reading a book, and we can sleep peacefully without damaging our eyes.
Use blue light blocking glasses.
Blue light blocking glasses are a trend these days. However, the function they serve is much more important than making us look stylish.
Blue light blocking glasses minimize blue light exposure whenever we look at our computer screens, phones, or other digital devices. We can wear them at our work hours while working on computers and at home when we are busy watching Netflix or using our phones.
Choose house illuminating sources that have a warm tone.
As said earlier, it’s not only phones and computer screens that emit blue lights. LED and other fluorescent bulbs are an equal culprit.
Therefore, experts suggest the use of light bulbs that gives off warm white light. Similarly, it’s a good idea to avoid bulbs with a cool tone or daytime like brightness.
Installing software and apps that tone down blue lights
There are millions of apps and software available to minimize the blue light emission from our digital devices. These software tones down the screen brightness and blue light emission after the sunset.
Using screen covers for laptops and computer screens
There are plenty of screens covers and blue light blocking shields available that, when applied, blocks excessive blue light emission to much extent.
Not only for more giant screens, but these covers are now available for smartphones and other smaller devices too.
Using night-shift mode on smartphones
Almost all of the smartphones now come with an option of shifting to night-mode after sunset. These night-shift modes adjust the color temperature of our digital screens to make it less jarring.
We can program our phones to switch to might-mode automatically, or we can do it manually from the settings option.
